Ball valves have a straight configuration and are suitable for many process services in the Oil & Gas, LNG, Chemical, Petrochemical, Power Generation, Marine & Offshore Industry, starting from drilling, mining and extraction to refining, petrochemistry, final transportation and pipeline distribution. ERREESSE production range includes Trunnion ball valves, Floating ball valves and Needle monoflange valves. Trunnion Ball Valves Floating Ball Valves Needle Valves

Trunnion Ball Valves Trunnion bounded by trunnions which do not allow axial displacements of the ball itself in the flow direction; line pressure compresses the seat onto the ball , the contact between surfaces generates the valve sealing. Trunnion standard construction ensures automatic cavity relief in case of overpressure in the body cavity; these valves can be selected for a wide range of applications with no specific limits to sizes and pressures. ERREESSE production range includes control valves with V-port and Cage Ball design which are designed according to IEC 534/ISA S75 and meet...

Construction One, two or three piece Port Reduced bore, full bore or fully piggable Stem retention Anti blow-out stem Leakage rate ISO 5208 Antistatic device Included, the ball valve design includes an electric conductive connection between the internal parts of the ball valve and the body, providing the anti-static function. Pressure relief Automatic cavity relief to prevent overpressure in body cavity (self-relieving seats) Sealing Bi-directional, Double block & bleed (DBB) with sealing in both directions (DIB-1&2 upon request) Drain Vent Stem grease...

Floating Ball Valves Floating ball valves have the obturator free between two soft inserts; under pressure the ball compresses the downstream soft insert to allow sealing; these valves are recommended for use in clean services with limited sizes and ranting. ERREESSE production range offers a wide selection of models and constructions suitable for use in chemical, hydrocarbon and critical process industry applications. Side Entry & Top Entry • Threaded body • Split body • Seal welded body • Modular body (DBB) Needle Valves Needle valves have no ball and are mainly used pressure fluctuations...
